Here is a list of most racing fuels  
http://www.ridgenet.net/~hideseng/dc_list.htm , note the asterisk. It may be 
helpful to some. I remember last year Sunoco caused a big stink when they 
changed the formula in their unleaded race fuel that is the spec fuel in Grand 
Am, ALMS, ect. Well apparently there was enough ethanol in it to corrode a lot 
of fuel system, and a lot of racers didn't know about it. Well everyone soon 
knew about it when they all put it in their cars, only to have their fuel cells 
deteriorate. It also does seem everytime they ban a certain dangerous chemical 
in a fuel, the new chemical that replaces it is even more dangerous and 
corrosive. It totally defeats the purpose of the original ban. 
 
Also for those with enough patience, time, and interest these two threads are a 
decent read, http://www.coloradoscca.org/prodcar/viewtopic.php?t=4080&start=0 
it's main topic is the spec fuels at the Runoffs, but they do talk about 
additives somewhat and the use of "super 
fuels".http://www.coloradoscca.org/prodcar/viewtopic.php?t=3946&start=0 just 
more discussion of what fuels are used and some more on "super fuels".

Actually, the stringent fuel regs mean more weird additives, not less. Most
low-octane pump gas products won't pass SCCA dialectric tests. The simple
additives can't be used. The aim is to eliminate the highly toxic ones. The
end result is all kinds of weird rocket fuel being used to get past the test
and still deliver 105-plus octane or octane equivalent. Two years ago when I
running a Radical in DSR, I got some stuff at Laguna (or maybe Sears) that
smelled like shoe polish, and passed the test for SCCA a few weeks later but
took on some of the color from my poly fuel can. Yikes. 

Conversely, the stuff I got from Pacific Raceways when they first put the
new big aboveground fuel tanks in looked and smelled like normal gasoline,
and worked fine, but I had to wash my fuel cans out with Avgas and fill and
pump Avgas through my fuel cell to get fuel to pass the dielectric test
after using it. About had me pulling my hair out. I got DQ'ed on an easy win
from fuel testing after the race.

With SCCA's stringent fuel regs -- and SCCA is not the only sanctioning body
taking a hard line on fuel, and those making racing gas know it -- I'm
skeptical of additives even being there to do such things. I'd be more
suspicious of quality control of the floats themselves (also explaining why
older ones are better).

We get so much aftermarket crap nowadays that cannot hold a candle to the
original....
